Philosophies of nutrient management in organic production systems focus on maintaining agricultural productivity with minimal inputs ( Elmaz et al., 2004 ; Stockdale et al., 2001 ). The end goal of nutrient management in organic agriculture is to

Tomatoes, cultivar `Mountain Pride', were evaluated for productivity, post-harvest qualities, and pest populations in three different production systems. These included a conventional, high chemical input system with prophylactic applications of pesticides and fertilizers; a reduced chemical input system that used pesticides only as needed; and a transitional organic system that followed the guidelines of the Organic Farmers Association of New Jersey. No significant differences were observed in either the high input or low input system despite a reduction in synthetic pesticide and fertilizer use. Organically produced tomatoes yielded significantly less than the other production systems in terms of total yields. Average fruit size was increased, however, along with the percentage of tomatoes with diameters larger than 7.7 cm. Differences in pest populations were noted between the plots.

Land application and landfilling are the most common destination for biosolids in the United States. When properly treated and managed in accordance with the existing state and federal regulations and standards, biosolids are safe for the environment and human health. Application of biosolids in vegetable production as an organic amendment to soils can increase plant growth and produce comparable crop yields with less inorganic nutrients than a standard program of commercial synthetic fertilizers. No application rate of treated biosolids alone will produce crop yields equivalent to commercial fertilizers. Biosolids may be used in conjunction with fertilizer thus lessening the application rate required. The major obstacles to public acceptance are issues concerning water pollution, risk of human disease, and odors. Additionally, heavy metals are an issue of bias with public perception. To ensure safe use of biosolids to a vegetable production systems the agronomic rate (nutrient requirement of the vegetable crop grown) should be calculated before application for the specific crop.

production systems were investigated in New Hampshire many years ago using open-pollinated varieties ( Loy and Wells, 1975 ), but the recent hybrids developed for New England conditions have not been tested in tunnels ( Loy, 2013 ). The objective of this
